UNCX Vesting Pool Exploited; Loss Estimates Vary Between Sources
A vulnerability in UNCX's Vesting V2 contract allowed attackers to exploit a share-accounting flaw and drain pooled tokens across multiple chains. Loss estimates range from $86,000 to $1.5 million depending on the source and scope of chains affected.

The Exploit Mechanics
The UNCX Vesting V2 exploit centered on a share-accounting flaw that permitted attackers to inflate their claims on tokens held in communal pools. According to Gonçalo Magalhães, head of security at Immunefi, the vulnerability allowed bad actors to misrepresent their ownership stake and withdraw more than their proportional share of pooled assets. One confirmed transaction moved five different tokens out of the affected Ethereum contract.
Conflicting Loss Figures and Scope
Security firm Blockaid pegged the loss at approximately $86,000 tied to the single identified transaction on Ethereum, where the contract retained roughly $3.25 million in assets post-exploit. Immunefi's security chief, however, reported total losses of about $1.5 million drained across four chains, suggesting either additional exploitations beyond the single flagged transaction or a broader attack surface than Blockaid's initial assessment captured. The discrepancy may reflect different methodologies for calculating stolen value or incomplete visibility into all affected pools at the time of reporting.
Ongoing Status
The Ethereum-based vesting contract remained operational with substantial liquidity intact, though the vulnerability's multi-chain presence indicated potential exposure on other networks. UNCX did not immediately announce a comprehensive remediation timeline across all affected chains.
Why It Matters
For Traders
Users with deposits in UNCX vesting pools face immediate withdrawal risk until the flaw is patched; verify liquidity status before attempting claims.
For Investors
Share-accounting vulnerabilities in pooled protocols undermine the trust model; this class of bug may prompt broader audits of similar DeFi mechanics.
For Builders
Vesting and staking pool designs must isolate user share calculations from user-controlled inputs; this exploit is a textbook example of incorrect accounting separation.
